    how to use get_file_list and get_file in C# using CDRonDemand web service
     i have tried following 

    CDRonDemandService cdr = new CDRonDemandService();
     ArrayOfFileName af = new ArrayOfFileName();
    af = cdr.get_file_list("200912030601", "200912030632", true);

    it gives me error

    The request failed with an empty response.

    public class BruteForcePolicy : System.Net.ICertificatePolicy
            {
                public bool CheckValidationResult(System.Net.ServicePoint sp, System.Security.Cryptography.X509Certificates.X509Certificate cert,
                        System.Net.WebRequest request, int problem)
                {
                    return true;

            public CDRonDemandService(string ccmIp, string user, string password)
            {
                //System.Net.ServicePointManager.CertificatePolicy = new BruteForcePolicy();
                //System.Net.ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback;
                this.Url = "https://" + ccmIp + ":8443/CDRonDemandService/services/CDRonDemand/";
                this.Credentials = new System.Net.NetworkCredential(user, password);
